CEQAT-DGHS Interlaboratory Test Programme for Chemical Safety - Need of Test Methods Validation

  • Safety experts, manufacturers, suppliers, importers, employers or consumers must be able to rely on the validity of safety-related test methods and on correct test results and assessments in the laboratory. Via the eChemPortal lots of data from the REACH registration dossiers are available. However, the quality and correctness of the information remains in the responsibility of the data submitter. Unfortunately, we found more or less appropriate information on physicochemical properties and concluded that more quality or adequacy of any data submitted will be needed. Interlaboratory tests play a decisive role in assessing the reliability of test results. Interlaboratory tests on different test methods have been performed by Bundesanstalt für Materialforschung und –prüfung (BAM) and Physikalisch-Technische Bundesanstalt (PTB) in collaboration with the QuoData GmbH during the last 10 years. Significant differences between the results of the participating laboratories were observed inSafety experts, manufacturers, suppliers, importers, employers or consumers must be able to rely on the validity of safety-related test methods and on correct test results and assessments in the laboratory.

Interlaboratory tests play a decisive role in assessing the reliability of test results. Interlaboratory tests on different test methods have been performed by Bundesanstalt für Materialforschung und –prüfung (BAM) and Physikalisch-Technische Bundesanstalt (PTB) in collaboration with the QuoData GmbH during the last 10 years. Significant differences between the results of the participating laboratories were observed in all interlaboratory tests. The deviations of the test results were not caused only by laboratory faults but also by deficiencies of the test method. In view of the interlaboratory test results the following conclusions can be drawn: • To avoid any discrepancy on classification and labelling of chemicals it should become state of the art to use validated test methods and the results accompanied by the measurement uncertainty. • A need for improvement is demonstrated for all examined test methods. Thus, interlaboratory tests shall initially aim at the development, improvement and validation of the test methods and not on proficiency tests. • The laboratory management and the practical execution of the tests need to be improved in many laboratories. • The term "experience of the examiner" must be seen critically: A "long experience with many tests" is not necessarily a guarantee for correct results.zeige mehrzeige weniger
